Improved dynamic-range single-mode OTDR at 1.3µm
A high-performance single-mode optical time-domain reflector (OTDR) incorporating a new low-noise receiver design utilising a PIN diode detector and a transimpedance amplifier is described. With a 1.3 µm laser diode source a dynamic range of 30 dB one way is achieved, and using an Nd:YAG laser sourc...
